Six successive 3600 second frames were collected at a sample temperature of 4°C and a solute concentration of 1.4 mg/ml. The data were normalized to the intensity of the transmitted beam and radially averaged and the corresponding scattering from the solvent-blank was subtracted to produced the scattering profile displayed in this entry.",
